As a “guarantor”, to what extent do I need to be responsible?

The “guarantor” for the visa application is the person who resides in Japan and makes a promise to the head of the embassy / consulate (the Japanese ambassador/ consul-general, etc.) to the effect that the visa applicant will stay legally in Japan. The responsibilities of the guarantor only entails moral responsibilities and does not entail legal responsibilities like that of the “guarantor” in the Civil Code. However, if it is recognized that the guaranteed matters (expenses for the applicant’s stay in Japan, return travel expenses, compliance with laws and regulations) have not been performed rightly, that person would lose credibility as a guarantor in subsequent visa applications. Also, be aware that if the guarantor or inviting person made a false statement in the documents about their relationship to the visa applicant or the purpose of visit, or if that caused terrorists to enter Japan or crime such as human trafficking, they may be held criminally responsible.
